What is the basic unit of life?
The Cell
What is the smallest particle of an element called?
An Atom
What are the two types of electric charge?
Positive and negative
What galaxy is Earth located in?
The Milky Way Galaxy
What type of animal does Mr. P have in his office?
Fish
Which organelle is responsible for producing energy in cells?
The Mitochondria
What is the difference between an element and a compound
An element is made of one type of atom; a compound is made of two or more elements chemically combined.
What unit is electric current measured in?
Amperes (A)
What force keeps planets in orbit around the Sun?
Gravity
Where does Science 10 go on a field trip each year?
Ripley's Aquarium
Name one difference between plant and animal cells
Plant cells have a cell wall and chloroplasts; animal cells do not
Give the chemical formula for water
H₂O
In a series circuit, if one bulb goes out, what happens to the rest of the bulbs?
They all go out (the circuit is broken)
Why do we experience day and night on Earth?
Earth rotates on its axis, causing different sides to face the Sun
What three classes does Miss Oliveira teach?
Science 10, Biology 11, Biology 12
What is the function of the mitochondria and why are they sometimes called the "powerhouse of the cell"?
They break down glucose to release energy (ATP) for the cell’s activities
What is the difference between physical and chemical change? Give one example of each
Physical change = no new substance formed (e.g., melting ice). Chemical change = new substance formed (e.g., rusting iron).
Calculate the resistance if a 12 V battery produces a 2 A current in a circuit
R=V/I=12V/2A=6Ω
What is a light year and why do astronomers use it instead of kilometres?
A light year is the distance light travels in one year. It’s used because space distances are so large that kilometres are impractical
Who won the 2025 UEFA Champions League?
PSG
Explain how the respiratory and circulatory systems work together to deliver oxygen to body cells
The respiratory system brings oxygen into the lungs; the circulatory system carries oxygen in the blood to body cells.
Using the periodic table, predict whether oxygen is a metal, non-metal, or metalloid, and explain your reasoning
Oxygen is a non-metal; it is found on the right side of the periodic table, is a gas, and does not conduct electricity.
Explain how Ohm’s Law relates voltage, current, and resistance, and why it is important in designing electrical systems
Ohm’s Law: V=I×RV = I \times RV=I×R. It shows how voltage, current, and resistance are connected, helping engineers design safe and efficient circuits.
Describe how the Big Bang theory explains the origin and expansion of the universe.
The universe began from a single, extremely hot and dense point about 13.8 billion years ago and has been expanding ever since
Name Miss Oliveira's favourite soccer team.
